Cylinder Question

So I’m getting my first pump but stuck on deciding between 2 cylinder sizes. I looked at the chart and I believe I should be using 1.75” since I’m 5” girth mainly but my bottom is closer to 4.5”. I’m mainly going for girth so I was thinking about going 2” instead. Any insight would be appreciated!

I’m 6” girth and my tube is 1 7/8” . You may have trouble with sealing at the base or having your balls sucked in. There’s posts on the forum discussing this.

Sheesh, what girth did you start at? I would think that you don’t have much expansion at that point to increase girth more. I’m guessing with your comment I should go with the 1.75 then?

That sizing chart is a little misleading- it assumes the base is the thickest part of your penis. Select your cylinder size based on the thickest part of your penis: glans, mid or base shaft. A 2” i.d. cylinder fits a maximum 6.28” girth, so functional 5.5”-6” girth. A 1.75” i.d. cylinder fits a maximum 5.5” girth.
